FORMING A PERFECT COMBUSTION AND PREVENTING THE FORMATION OF SMOKE.

SPECIFICATION forming part of Letters Patent No.339,600, dated April 6,1886.

Application filed August '28, 1884.

To aZZ whom it may concern.-

Be it known that I, JAlIIES A. Tamer, a citizen of the United States,and a resident of Chicago, in the county of Cool; and State of Illinois,have invented certain new and useful Improvements in Forming a PerfectCombustion and Preventing the Formation of Smoke, of which. thefollowing is a specification.

The object of my invention is to provide a steam-boiler with suchappliances that the heat will be more evenly distributed and carried tothe rear of the boiler, for the purposes of consuming the gases whichusually pass through the lines as smoke and issue unburned,- and for thefurther purpose of preventingthe formation of scale. It is also a partof the object of my invention to dispose of a part of or all theproducts of combustion.

I have shown my invention as applied to a boiler of the structureusually employed for portable or marine engines.

Figure 1 is a sectional view of a tubular boiler with my attachmentsapplied. Fig. 2 is a rear view, and Fig. 3 is a front view. Figs. 4 and5 are details of the rear pipes and front T s.

Like parts are indicated by like letters in all figures.

A is the boiler; B B, thefiues; O 0, two large pieces of gas-pipe,

are in the position shown. E E are pieces of pipe in the shape of Ts. FF are short nipples. G is the smoke-slack; H, the firebox; I, thegratebar; J, the front of the boiler; K, a damper in the smoke-stack; L,a pipe leading from a point below the damper to a fan, )I; N, a pipeleading from the fan to the perforated pipe 0, which opens into thefront and sides of the grate-bar; P, a pipe discharging into the openair or elsewhere at will; R and S, caps on the Ts and the rear pipes tocover the ends thereof.

It will be seen that great changes can be made having perforations D Dopposite the ends of the fines when the pipes Serial No. 141,657. (Nomodel.l

in the form, structure, and arrangement of these parts without departingfrom the spirit of my invention, which will be seen to be in the meansfor returning the gases successively back and forth through theboiler-fines and in combining such means with the fan.

The use and operation of myinvention is as follows: The gases which areformed by and escape from the tire on the grate-bars pass backwardthrough the lower flues. At the rear they pass into the lower transversepipe, U

and thence into the next row of flues. The circuit is thus kept upthrough the flues, Ts, nipples, and rear pipes until the stack isfinally reached, when they pass out through the pipes into the open airor into the fan. By the fan they are discharged into the front of thefire, or into the open air or water, as may be de sired. The fancontrols and supplies the draft. When it is desired to clean the fines,the caps on the ends of the Ts may be removed and the brush be inserted.In a similar manner the rear transverse pipes may be cleaned by removingthe end caps. In this manner the products of combustion are consumed inthe fines of the boiler by reason of passing through them successively,and the residue is disposed of by the fan.

It is plain that the T-pipes may either end.

The fan may be run by a small engine. Vhat I claim, and desire to secureby Letters Patent, is-

In aboiler, the combination of the lines with rear transverseconnecting-pipes and with front Ts, whereby the flues are so connect-edthat the gases pass back and forth through them in the manner shown.

In witness whereof I have hereunto set my hand this 18th day of August,A. D. 1884.
